Very often, bitumen emulsion is used for surface treatment of asph alt and waterproofing of various structures - a kind of system in which the particles of the main component are presented in the aqueous phase in the form of separate elements. So that such an environment does not have a gluing effect, all kinds of additives are actively used - emulsifiers. It cannot be denied that bituminous waterproofing is beneficial in terms of resource saving and environmental friendliness. Usually, specialists in the process of work encounter different brands of the base substance. At the same time, the obtained compositions can differ significantly from each other in properties.
Any bituminous emulsion requires the addition of a solvent, and its amount must be fairly accurate. Otherwise, precipitation of individual components or excessive dissolution of the mixture may occur. The solvent is used as an agent that reduces the degree of viscosity of the composition. With regard to the water contained in such waterproofing, cationic mixtures are less sensitive to added volume than anionic counterparts. The last of themreact intensively to the amount of impurities contained in the added liquid.
In the manufacture of mixtures, a special installation for the production of bitumen emulsion is used, which has a complex structure. It consists of: the main unit with a colloid mill, electronic control systems, dosing lines for water and bitumen, containers for storing various materials, as well as pipelines and pumps. The work is carried out according to the principle of thorough mixing, which implies further emulsification of the composition. The quality of the final product is highly dependent on the homogeneity of the mixture and pre-treatment.
Virtually all equipment units are made of materials that are not subject to corrosion, which allows to achieve maximum service life. This is especially true of units and parts that have direct contact with the aquatic environment. Currently, only automated equipment is used, which makes it possible to obtain a quality product when the bitumen emulsion meets all requirements. The quantity and characteristics of products are measured by special sensors. Based on the fact that the properties of the finished mixture depend on emulsifiers, devices appear in production that can absorb components in two directions.
Before the bituminous emulsion is applied to the surface, the substrate must be carefully prepared. To do this, they get rid of the old coating and various debris by leveling potholes larger than threemillimeters. Next, priming is carried out with an emulsion composition. The type of surface to be treated has a special effect on the consumption of the mixture. Looking at the packaging, you can see the average consumption of the product. When the water from the solution evaporates, a thin film of bitumen will remain on the surface, protecting the next coating.
